BEARING BOX.

Application mea January 26, v1922. serial No. 531,998.

To all whom t may concern:

13e it known that I, Bronnen L. NEUBERr, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Bearing Boxes, of which the following is a specification, reference being had to the accompanying drawing. l

My improvement relates particularly to bearing boxes adapted to receive two shafts or axles which cross each other. In the form hereinafter described my improvement is applied to such a bearing box having a single body and two 'caps `or cap plates, one of said caps being located at one side'and the other at the other side of said body and said caps being at right angles to each other.

The object of my improvement is to provide more effective and more durable and convenient means for securing` said caps to said body. In the form of such bearings heretofore used, each of said caps has been fastened to the body by two bolts extending through the body yand the cap and by two stud bolts threaded into the body and extending through the adjacent part of the cap and receiving nuts outside of the cap. Onejof the uses of such bearings has been on logging locomotives for connecting a longitudinal power transmission shaft to the transverse axles of the trucks of the locomotive. Large power is transmitted through said transmission shaft to the axles, and consequently there is large straiiron the bear` ings and on the bolts whereby the caps Vare intended'to be held in place. In practice, the stud bolts above-mentioned frequently break. It has been found that if one of those bolts breaks, additional strain is put upon the companion stud bolt which is applied to the same cap, and that then that second bolt also breaks. And in most cases the fracture of the stud bolts is close to the body of the bearing. When such breakage occurs, the locomotive must be raised andthe truck`removed. Then the pieces of the broken stud bolts must be removed and new bolts inserted. Usually the removal of these pieces is diiiicult and tedious, the part of the stud bolt remaining seated in the body of the bearing being difficult to engage for re` moval. Sometimes `it must'be removed by drilling. i f kI regard the'fracture of these stud bolts'as being due to the -fact that they are short and are so seatedV as to concentrate strains and vibrations on the bolt close to theface of the body lof the bearing. The bolts which extend through the body and one of the caps are longer and i'nthem -there is nosuchtconcentr-ation of strains o rsvibrations, and those bolts seldom break. The object of my improvement is to eliminate the short stud bolts and substitute bolts which will have such length 4as to avoid concentration vof strains in one part ofthe bolts. For. the four short stud bolts I have substituted one long yU-bolt.

In the accompanying drawings,

Fig. l is a'plan showing parts of two trucks ofa logging locomotive, they middle section of the power transmission shaftbeing broken away; y y

Fig., 2 ,is a detail 'plan of the right hand part o'f the left hand truck of Fig. 1, one of the track wheels being omitted and other parts being broken away; i

Fig. 3 is an upright section on the line, 3-'3, of Fig. 2,l looking in the direction of the arrow; v 1' Fig, L is an upright section on the line, 4 4, of 2, looking in the direction of the arrow; Fig. 5 yis an upright section on theline, 5 5, of Fig. 2, looking in the direction of the arrow;

Fig. 6 is a perspective ofthe U-bolt'which extends through the body yof the bearing and engages the two cap plates.

Referring to said drawings, A, A lare track wheels, and A1, A1 are axles supported by said wheels. lThe four wheels and the .two axles at the right in Fig. l belong to one truck ofa loggingjlocomotive, and the four wheels andthe two axles at theleft in the same figure belong to another truck 4ofthe same locomotive. On each` truck Yis ahorizontalpower transmission` shaft extending crosswise vover the two axlesY of` that truck. Between said shafts is a middle section, B2, of the transmission shaft (partially` broken which has its endsjoined to the shafts, B, by means of universal Cou` plings, B1. Power is applied tothe middle section, B2, inthe well known manner, fo

rotating said shaft. Y

At'each axle a double bearing box, C, sur` rounds the axle and also the transmission shaft, B. And adjacent each side bearing box .a gear wheel, B3, surrounds and is fixed Vtothe transmission shaft and meshes with a' gear wheel, A2, which surrounds and is fixed i to the adjacent axle, A'lhese two gear` wheels are of skew bevel form.

The bearing box, comprises a middle body, C1, and an upper cap orrcap plate, C2, and a lower cap or Vcap plate, C3, and the bolts whereby said vbody and said caps are held to each other. Y

The bevelV gear wheel, A2, is placed close to the transmission shaft, B, inv order that the bevel gear wheel, B?, vwhich meshes with the wheel, A2,? need not be objection- Vably vvlarge-it is preferably smaller than the wheel, A2. In order that the wheel, A2, may thus be near the transmission shaft, the part of the body, C1, ofthe bearing box which lies between said Vwheel and said if shaft is of'relatively limited thickness. But

at the opposite side of the transmission shaft, the body, C1, is extended along the a.x'le,"A1,. far enough to project beyond the uppercap, C2, whereby'room is made for inserting two ordinary bolts, C5, downward througi the body and through the adjacent end of thelower cap. (See Figs. 2 and 4) The wheel, B3, is similarly placed f close to the axle, and the body, C1, is in the same manner extended along said. shaft,

whereby room is made forinsertingtwoY ordinary bolts, C4 and CG, upward through the body and the upper cap, C2. Thus it will bek seen that the body, C1, has two extensions or arms `at right angles to each other, whereby the` body is made L-shape.

- And it will be seen that each cap is elonfgatedto reach over one of the body extensions, kwherebysaid caps lie at right angles to each other and each extends beyond the Y other to permit extending boltsthroughrthe throughythe body, C1, and through the upper cap, the nuts Ybeing yon thefupper face Y of the cap. ,The lower face of the part of the cap, C3, which is adjacent the bevel gearwheel, A2, is rounded. A YU-bolt, C6, surrounds said part of said cap and extends upward through the body, C1, and

f track wheel, A.

through the upper cap, C2, the nuts, C7,

for said bolt being on the upper face of the v upperY cap. 0n account of the inclination of the upper cap, each arm of the U-bolt is bent at, C8, (Figs. l and 6), in` order A1, at the side of the bearing opposite the f wheel, A2, andv extendingl to the adjacent n win be noted that vthe ufbn Vengages;

both caps and that said bolt is relatively long. lin a locomotive to which I Vhave applied this iniprovemenarthe total length ofthe U--bolt is about 30 or 36 inches, the.

longer part of the bearingboxbeing about 16 inches and said box weighingabout 150 or 160 pounds. rlhe U-bolt takes the place of the four stud bolts previously used. On

the trucks ofv such a locomotive which VI have operated, the. stud bolts frequently broke, and much labor and timewere required for replacing the broken bolts. After substituting the U-bolts, the locomotive has been operated severalV months without breaking the U-bolts nor the ordinary bolts.

I claim as myinvention,
